What is processing gain?
The process gain (or 'processing gain') is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).For example, if a 1 kHz signal is spread to 100 kHz, the process gain expressed as a numerical ratio would be 100,000/1,000 = 100. Or in decibels, 10log10(100) = 20 dB.
An emitter follower has a voltage gain that is?
.7v less than unity for DC operation but unity for AC.
Common collector amplifier does not have voltage gain but still provide power gain?
It still has a current gain significantly high though the voltage gain is close to unity.
Why consider only 3dB for bandwidth calculation?
3dB of gain rolloff is a linear reduction of gain by a factor of 2. That makes it a good reference point.
How gain varies with bandwidth in an op-amp?
The gain of an op amp varies with frequency. After an op amp reaches the half-power point, the gain falls appreciably. And then once it hits the transition frequency, the op amp no longer provides any gain.
